1. Introduction The use of multiple X-band dual-polarimetric radars to study the precipitation structure has accelerated in the past decade, largely due to its lower cost, small size, and ability to provide high-resolution observations of the lower troposphere. Other advantages include the continuous improvement in X-band procedures for rainfall estimation, multisensor data fusion for overlapping coverage areas, and effective attenuation correction [for a review, see Bringi et al. (2007) ]. In

relevant to flood prediction. In section 3 , we describe our spatiodynamic data evaluation framework for space-based precipitation estimates. Section 4 describes data used in this study, and section 5 presents the results of the study using the IFloodS experiment dataset. Finally, we discuss the results with respect to the findings that arose when we used the proposed framework. 2. Review of flood forecasting using space-based precipitation estimates During the past decade, multiple efforts have

1. Introduction Single-polarization (SP) radars have been used to estimate precipitation quantities for several decades (e.g., Wilson and Brandes 1979 ). During this period, the research community has extensively examined the limitations of these instruments and developed methods to improve quantitative precipitation estimation (QPE; see, e.g., Austin 1987 ; Smith et al. 1996 ; Pereira Fo. et al. 1998 ; Krajewski and Smith 2002 ; Villarini and Krajewski 2010 ; Kitzmiller et al. 2013

764 mm, although we believe CMORPH-adj underestimates the precipitation. Furthermore, considering the fact that more summer soil water stress was experienced in the central United States during the last decade (thus more ET) and both NLDAS-2 and the MODIS product MOD16 ( Mu et al. 2011 ) estimated the mean annual ET of ~600 mm, the reference ET of 627 mm is most likely within ±5% of the truth. The residual (runoff + ET − precipitation) in the modeled water balance as indicated by Table 2 can be
